Non-recyclable waste, due to its high calorific value (over 6 MJ / kg), is a problem for most waste treatment plants, because according to the law from 1 January 2016, it cannot be stored. RDF as a product created from non-recyclable waste occurring in the form of, for example, a flake, can be used in energy recovery processes, such as pyrolysis. This method is environmentally friendly because, unlike combustion, the process takes place in a limited amount of oxygen.

Description of the technology:

  1. Specially prepared waste is subjected to a pyrolysis process inside an airtight reactor. Pyrolysis temperature range reaches from 800°C to 1000°C.
  2. High-calorific syngas produced in the process is dedusted and cleaned up from aggressive chemicals (Cl, S, F).
  3. Part of the produced syngas is used to power the pyrolysis burners making the process autothermal.
  4. Clean syngas is used as an alternative gas fuel to power an internal combustion engine.
  5. Silnik stanowi jednostkę kogeneracyjna do wytwarzania energii elektrycznej i energii cieplnej.Combined Heat and Power engine generates electricity and useful heat.
